18 cups, 4.5 quarts. A good average to figuring out snow to water ratio is 12-1. So there 1/12 of a cubic foot of snow will be the volume of water. An ounce is 1 inch sq. 12x12 is 144 cubic inches of water. 144 divided by 8 ounces to a cup is 18 cups. There fore 4.5 quarts.
Gold.
It varies, but we can make an estimate based on the weight of water and how much water is contained in 'fresh fall' snow. Water weighs 1000Kg per cubic meter (at 4 degrees Celsius), and 'fresh fall' snow melted to water becomes approximately 1/10th its original volume. So, we can estimate that a cubic meter of snow weighs about 1/10th that of water = 100Kg. However, snow is just elaborate ice crystals, and so these will change form many times depending on temperature and time, so a cubic meter of snow may become heavier as time passes due to compacting ice crystals. Still, it pays to knock all the snow and ice off your car, as it will always contain some sort of weight, and will reduce fuel economy because of this.
The lead is more dense. Just so you know the volumes listed before each material are irrelevant - each one theoretically has a constant density no matter how much of it there is.

To convert cubic feet of snow to gallons of water, you need to consider the density of snow. Snow typically has a density of about 10% of water, so you can multiply the cubic feet of snow by 0.1 to get the cubic feet of water, and then multiply by 7.48 to convert to gallons.
On average, a cubic yard of snow can weigh anywhere from 500 to 800 pounds, depending on factors such as snow density and moisture content.
Melted snow is water. Water, because it is a liquid, is hard to weigh as you normally only weigh solids. Liquids would have to be measured litres or gallons. So the answer to that question would depend on how much snow had actually melted- eg. 12% ice and 78 % is water and 10% is debris caught in the snow as it fell
That's going to depend on the density, i.e. the water content of the snow. Themore dense snow will have less nitrogen, since there's no nitrogen in water at all,only in the air, of which there's more in fluffy snow than in the heavier kind.
Freshly fallen snow has a density of approx 50 kg per cubic metre but for compacted snow the density can increase to 200 kg per cubic metre. So the answer will depend on the kind of snow you are asking about.
On average, 1 gallon of water would convert to roughly 0.133 cubic feet of snow if the snow's density is around 20 pounds per cubic foot. However, the exact conversion can vary based on factors such as the snow's density, moisture content, and temperature.
Snow is not uniform for density so you would have to weigh the cubic foot you are interested in. Each pound or kilogram would be composed of 1/9 hydrogen and 8/9 oxygen (by mass) since the molecular weight of water is 18, the atomic weight of hydrogen is 1 and the atomic weight of oxygen is 16. Based on 1 cubic foot of snow being about 10% the weight of a cubic foot of water, it would weigh approximately 6.25 pounds and contain about 5.56 pounds of oxygen.
